Reservoir ink-filling machine

Abstract

Embodiments of ink-filling devices are described. An ink-filling device may include a feeding-stock arranging track configured to stack workpieces in a single file. An ink-filling needle is configured to move from a first position opposite from the feeding-stock arranging track to a second position within the feeding-stock arranging track. A push rod is configured to move from a first position opposite from the feeding-stock arranging track to a second position within the feeding-stock arranging track. The devices may be used for filling with ink the absorbent wrap-around cores used in writing instruments.

Description

technical field [0001] The invention relates to an ink filling device, in particular to a roll core ink filling machine. Background technique [0002] At present, most of the highlighters, markers, and whiteboard pens that are popular in the market use roll cores to store ink. The nib cover is inserted into the roll core, and the roll core needs to be filled with ink before use. The traditional method of filling ink is to bundle core-spun rolls into bundles of core-spun bundles first, and then the operator takes the bundle of core-spun rolls in one hand and the syringe with ink in the other hand, and then injects ink into the core-spun rolls one by one. However, the amount of ink injected into the cores of each roll is completely determined by the subjective judgment of the operator, which will lead to uneven ink filling in the cores of each roll, and the cores with less ink filling will reduce the writing length. The roll-spun core with a large amount of ink filling may c...

The traditional method of filling ink is to bundle core-spun rolls into bundles of core-spun bundles first, and then the operator takes the bundle of core-spun rolls in one hand and the syringe with ink in the other hand, and then injects ink into the core-spun rolls one by one. However, the amount of ink injected into the cores of each roll is completely determined by the subjective judgment of the operator, which will lead to uneven ink filling in the cores of each roll, and the cores with less ink filling will reduce the writing length. The roll-spun core with a large amount of ink filling may cause ink leakage and dripping during use; on the other hand, the efficiency of this traditional ink filling method is very low; Bind the roll cores into roll core bundles, and then inject ink into the roll cores manually, which requires a huge amount of manual work
